Kamailio packages are included in the official Debian Stable repository. At the time of writing the initial version of this tutorial, Debian Stable codename is Jessie, version 8.x.

The focus of this tutorial is to install Kamailio with MySQL backend.

apt-get update
apt-get install mysql-server
apt-get install kamailio kamailio-mysql-modules

Configuration files are located in /etc/kamailio/ folder.

The /etc/kamailio/kamctlrc is the configuration file for kamctl and kamdbctl. You need to edit it and set the SIP_DOMAIN to your SIP service domain (or IP address if you don't have a DNS hostname associated with your SIP service).

Set also the DBENGINE to be MYSQL and adjust other setting as you want.

The /etc/kamailio/kamailio.cfg is the configuration file for kamailio. Edit it to enable some of the features shipped with it.

To enable use of MySQL backed, user authentication and persistent user location, add after the first line:

#!define WITH_MYSQL
#!define WITH_AUTH
#!define WITH_USRLOCDB

To create the database structure needed by Kamailio, run:

kamdbctl create

Depending on startup system, you may have an /etc/init.d/kamailio script that you can use to start/stop kamailio.

First you should edit /etc/default/kamailio and adjust the setting for kamailio startup script, in particular the one that enables kamailio to start.

/etc/init.d/kamailio start
/etc/init.d/kamailio stop

If the default startup system is systemd, then kamailio can be managed via systemctl:

systemctl start kamailio
systemctl stop kamailio

First you may also need to edit /etc/default/kamailio and adjust the setting for kamailio startup script, in particular the one that enables kamailio to start.

If you edit the systemd unit file in order to add your own functions, you need to make sure that you make a copy of the unit file in /etc/systemd/system in order to avoid any updates in packages to overwrite your modified file with the standard one.

To add subscribers (users), you can use the kamctl command:

kamctl add userid password

Like:

kamctl add alice secret
